The winemaking process

 

 

A typical winemaking process is often very natural and requires minimal human intervention, however wine filtration plays a key role at certain stages. At the very beginning, the winemaking process starts when ripe grapes are harvested, crushed and then pressed, only finishing when a perfectly clear and aged wine is bottled. Filtration is used at key points and tends to get successively more refined throughout the process; beginning with a coarse clarification, before moving to more refined stages to polish the wine. The finest stage of wine filtration is through a final membrane which helps to control microorganisms which if left can prematurely foul the wine.

Gas management is also utilised within the winemaking process to control CO₂ and O₂ levels that can impact aroma and taste.


Gas management

Gas management is employed in several ways in a winery. From controlling dissolved gas that impacts quality, to sanitisation water for equipement.

Rough Clarification

Rough, polishing and ultrafine clarification steps remove any carry over of dead yeast cells from the fining stage along with hazes.

Final Membrane Filtration

Final filtration is required to create stability and prevent spoilage after being bottled. Final Filtration removes microorganisms and other contaminants that can spoil both hardy and delicate wines.

Water Pre-Treatment

Filtered water is used in a winery for rinsing, flushing, regenerating and sanitising equipment.
